The blog post details a new CNC controller I designed. I have probably designed 40-50 different controllers over the years, but this one has me really excited. My past controllers were generally application specific. My recent controllers have all been for the Grbl_ESP32 firmware. The I/O on the ESP32 is very flexible, but somewhat limited in pin count. There have always been enough pins to control the machine, but not enough to make a general purpose CNC controller that can target any machine.
